Railguns are a rubber-loaded style of speargun characterised by the rail or track that extends along the top of the gun barrel. This rail supports the shaft when loaded and guides it as it's fired. Due to their reliable and simple design, railguns are the go-to speargun style for most spearos.
There is a particular advantage with this style of gun over tube guns as you move into longer lengths, as it prevents your shaft from sagging. In a typical tube gun the shaft is supported at the mechanism where it's locked in, and at the muzzle. The shaft can begin to sag either in the middle of the gun or past the muzzle in longer lengths which can reduce shot accuracy. A rail overcomes this issue and ensures the spear flies straight from the muzzle.
